T0 at! whom it may concern:

Be it known that I, JEAN ANTOINE BIATHu the State of Pennsylvania, have invented a certain new and useful process for the manufacture ofgeiatine or gluefrom hides, animaltlesh,or from fish,and also an improved apparatus to be used in connection therewith; and I declare the following to be a specification thereof, reference being bad to the accompanying drawing.

The said drawing represents a vertical section through the center of my apparatus.

A closed vessel,A A, preferably of cast-iron, is constructed of the form shown,and provided with necks B and D, closed respectively by lids b and t. The under side of the neck D is perforated by small holes, as shown at e,whicb communicate with a subjacent compartment, E, having an outlet-pipe at u. Within the vessel A ls-a closed rectangular compartment, K, having pipes on and r for the entry and exit of steam, shelves G G, formed of gratings arranged upon an endless chain, it, which revolves around the compartment K, being actuated by the pinions n 11. These shelves are. pivoted so as to turn in a direction opposite to that of thcir'morement,which latter is indicated by the arrow. The supports g'g, however, slide upon the surfacevot the compartment K, prevent them from turning except when atthe point indicated at L, when the the support 9 has no bearing.- Th'e-vcssel A has exit-pipes at c and g, provided with cocks,

A vacuum-boiler, F,heated by a steam-jacket, N, and communicating by a pipe, 7:, witha condcnser,is arranged with its mouth beneath the discharging end of the neck I). The opening between the vessel A and theneck Disclosed by a, sliding door or register, (I, raised and lowered by a rack and pinion. The operation of the apparatus will be described in connection with the process to be used therewith, which has foritsobjectprimarilytheelimination from the substance treated of its oily and watery and bony portions and the separation of the gelatine from the residue, and, secondarily, the economical recovery of the chemical agents Patent No. 276,256, dated April 24, 1883'. l

used, as well as the preservation of the elite inated portions. The primary process consists in the subjection of the material to the successive action of solvents, accompanied by mecbanical treatment, and the distillation of the gelatine from the residue.

I take the substances to betieaterL-such as fish, animal-flesh, or refuse hides-"sent: them into small pieces, and introduce them into the neck 13 of the vessel A. The latter is filled with methylic alcohol (the wood-spirit of commeree) to the level of the pipe 0, and the substance to be treated. is received by the shelves .G and carried very slowly around until it;

reaches the opening in the neck D, when each shell, as its supportg passes "the end of the compartment K, falls downward, as shown at (i, and discharges its lead into the neck 1).- Here a great portion of the liquid is drained otfthrougb the opening in thebottom (,and is caught in the receptacle E, whence it is with drawn at u. The washed and drained substance is then discharged, by removing the lids t and f, into the vacuum-boiler F, when it is heated bythe steam-jackehaud the remaining liquids are driven off through the pipe 1:.

raise the temperature of the mass to-abont 120 I prefer during the steeping in the vessel K to 8 Fahrenheit, and for this purpose steam is adprocess,) which second treatment consists in steeping itin acetic acid while mechanically agitating it, as-betore, by means ofwhich the osseons portions are dissolved. The excess of acid is then drained oil, and the residue is heated in the vacuum-boiler 1* up to about;

212 Fahrenheit-deriving thegelatine in proper condition foruse. This completes the main or primary process of my invention.

The secondary processes have for their ob-' jectthc recovery of the solvents used as above and the conservation of the dissolved fate or acid s--such as oils, I taliethe methylic alcohol contaillhlgtho fats in sol'utiomand add thereto cold mil 1111- 'til all the fats are precipitated. After se g,

The aceticacid solutions remaining from the second stage of the main or gelailtl D cess containalhmnen'and salts of lime, ltreat these solutionswith subacetate of ki y means of which the albumen is preciiiitfl o then filter the'liquid residue through ehtlfl and decompose the'acetate of lime hjf a y of the ordinary processes, thus recovering he acetic acid in a condition fit for use scam In the geiatine process. p

In the processes above described WH equivalents for the solvents specified 11 51 used-as5 for instance, in place of disti g the fats by means of'methylic alcohol, tllfi Same result may he obtained by using acetoil n in place of dissolving the albnininons an seous portions in acetic acid other or may be substituted as solvents.

formic, oxalic, or pro'pi*l0IIic-- tially as specified;

from the aqueous solution, substau 3. The process of recovering acetic acid from its combination with albuminous and osseous matter by treating the compound with subacetate of'lead, filteringthe liquid residue through charcoal,an(1 subsequentlydecomposing such residue, substantially as specified.

4. The combination of the vessel A, having necks B and I), with the endless chain 2' and the pivoted shelves G, substantially as specified and shown.
